I have a love/hate relationship with magic mountain.  They have some great rides but terrible operations.  I usually go Sunday mornings as it is not that busy but it's a guessing game what rides will be open on time.  Viper opened really late, X2 went down early or opened late and went down, Scream went down (also 1 train ops forever), Ninja went down (1 train ops), Superman only running 1 side, craznity has been down a week and Riddlers revenge was down.  Twisted has been on 2 train ops for a few weeks.   I left the park at 1:00 pm with some rides in but frustrated that Magic Mountain doesn't care.
At least it is cheap to be a member.
